Cable assembly

摘要

A hybrid cable assembly includes a hybrid cable, tether tubes, and an overmold. The hybrid cable includes both electrical-conductor and fiber-optic elements. The tethers receive a subset of the elements from the hybrid cable at a transition location in the form of a chamber, and the overmold surrounds the transition location. The overmold is elongate, flexible, and has a low profile configured to pass through narrow ducts.

1. A cable assembly, comprising:
a hybrid cable comprising:
electrical-conductor elements comprising wire conductors;fiber-optic elements comprising optical fibers; andconductive armor providing a ground path of the hybrid cable; one or more fiber-optic tethers comprising optical fibers optically coupled to the optical fibers of the hybrid cable; electrical tethers coupled to the electrical-conductor elements of the hybrid cable, wherein the electrical tethers include a conductive shielding surrounding wire conductors electrically connected to the conductive armor of the hybrid cable, a chamber within which the wire conductors of the electrical tethers are coupled to the electrical-conductor elements of the hybrid cable and the optical fibers of the fiber-optic tethers are optically coupled to the optical fibers of the hybrid cable, wherein space within the chamber, unoccupied by fiber optic and conductive components, is filled with a dielectric filler; wherein the chamber electrically connects the conductive shielding of the electrical tethers to the conductive armor of the hybrid cable, thereby providing grounding for the assembly, and wherein the chamber is formed from a conductive material that serves as the electrical conductor connecting the shielding of the electrical tethers to the conductive armor of the hybrid cable; and an overmold surrounding the chamber, wherein the overmold is polymeric and provides flexibility to the assembly; and wherein the overmold is elongate, having a length at least five times the largest cross-sectional dimension of the overmold transverse to the length, whereby the overmold has a low profile configured to pass through narrow ducts.
